The suspension structure 500 is mounted on the heating body 100 and is used to apply resistance to the cover body 200 so that the cover body 200 can be suspended.

[0034] For the heating device 10 in the above embodiment, when heating is needed, the cover body 200 is rotated toward the open cover position, and the first side panel 300 and the second side panel 400 are moved toward the outside of the heating device 10; when the cover body 200 is rotated to the open cover position, the hovering structure 500 applies resistance to the cover body 200 so that the cover body 200 can hover in the open cover position, and the heating body 100, the cover body 200, the first side panel 300 and the second side panel 400 are correspondingly arranged to form a heating space, thereby reducing the heat loss rate and achieving the effect of heat preservation and energy saving. When storage is required, the first side panel 300 and the second side panel 400 are moved toward the inside of the heating device 10, and the cover body 200 is rotated toward the closed position; when the cover body 200 is rotated to the closed position, the first side panel 300 and the second side panel 400 are both stored between the heating body 100 and the cover body 200, so that the height of the heating device 10 is significantly reduced, which is convenient for storage, organization and placement, and improves the practicality of the heating device 10 and the user experience.

[0035] The heating body 100 can be configured as any structure used for heating in the prior art.

[0036] As shown in FIG4 , optionally, the heating body 100 includes a base 113, a mica board 114, an electric heating film 115, a rubber pad 116, a pressing plate 117, a display panel 118, a control board 119 and a bottom cover 120. A first concave cavity 121 is provided on the top surface of the base 113, and a second concave cavity is also provided on the bottom surface of the base 113. The mica board 114 is arranged in the first concave cavity 121. An electric heating film 115 is arranged on the mica board 114. A rubber pad 116 is arranged on the electric heating film 115. A pressing plate 117 is arranged on the rubber pad 116. The pressing plate 117 is fixed to the base 113 by screws. The control board 119 is arranged in the second concave cavity and fixed. The bottom cover 120 is fixed to the bottom of the base 113 to cover the second concave cavity. A second sink 123 is also provided at the head of the base 113, and the display panel 118 is mounted on the second sink 123.

[0037] Specifically, the bottom wall of the first cavity 121 is also provided with at least one mounting groove 124. The heating body 100 also includes rollers 125, the number of rollers 125 is the same as the number of mounting grooves 124, and each roller 125 is correspondingly installed in each mounting groove 124. The mica board 114, the electric heating film 115 and the rubber pad 116 are all provided with avoidance holes for avoiding the top of the roller 125. The pressing plate 117 is provided with a central hole, and the inner contour shape of the central hole is adapted to the outer contour shape of the mica board 114, the outer contour shape of the electric heating film 115, and the outer contour shape of the rubber pad 116. The pressing plate 117 is used to press the four side edges of the rubber pad 116, the four side edges of the electric heating film 115 and the four side edges of the mica board 114 onto the base 113 in sequence.

[0038] It should be noted that, in the process of opening and closing the cover body 200, the order between the rotation step of the cover body 200 and the movement step of the first side panel 300 and the second side panel 400 can be flexibly adjusted according to actual use needs. That is, the rotation step of the cover body 200 and the movement step of the first side panel 300 and the second side panel 400 can be performed simultaneously or one after another.

[0039] The first side panel 300 and the second side panel 400 can be foldable or non-foldable. Specifically, in this embodiment, the first side panel 300 and the second side panel 400 are made of a flexible material and are symmetrically arranged on opposite sides of the heating body 100 (the left and right sides will be described in detail below). When the cover 200 is in the open position, the first side panel 300 and the second side panel 400 are completely flattened.

[0040] As shown in Fig. 3 and Fig. 4, in one embodiment, the first side panel 300 and the second side panel 400 are both self-foldable structures. The first side panel 300 and the second side panel 400 are respectively located on opposite sides of the heating body 100, and are connected to both the heating body 100 and the cover body 200. The first side panel 300 and the second side panel 400 both have a folded state and an extended state. When the cover body 200 moves to the open cover position, the first side panel 300 and the second side panel 400 are both in an extended state, and are surrounded by the heating body 100 and the cover body 200 to form a heating space. When the cover body 200 rotates to the closed cover position, the first side panel 300 and the second side panel 400 are both in a folded state and are stored between the heating body 100 and the cover body 200.

[0041] As shown in Fig. 3, Fig. 4 and Fig. 5, further, a first storage cavity 211 and a second storage cavity 212 are provided on one side of the heating body 100 close to the cover body 200, or on one side of the cover body 200 close to the heating body 100. The first storage cavity 211 is arranged corresponding to the first side plate 300, and is configured to store the first side plate 300 when the cover body 200 moves to the closed position. The second storage cavity 212 is arranged corresponding to the second side plate 400, and is configured to store the second side plate 400 when the cover body 200 moves to the closed position. In this way, when the cover body 200 moves to the closed position, the first side plate 300 and the second side plate 400 can be correspondingly hidden in the cover body 200 or the heating body 100, without occupying additional height space, so that the height of the heating device 10 can be further reduced, thereby improving the practicality of the heating device 10.

[0042] Specifically in this embodiment, when the heating device 10 is in the heating state, the size of the heating device 10 is 370mm*320mm*210mm; when the heating device 10 is in the storage state, the size of the heating device 10 is 370mm*320mm*35mm;

[0043] Specifically in this embodiment, the cover body 200 includes an upper cover 217 and an inner cover 216. The inner cover 216 is located between the upper cover 217 and the heating body 100, and can be fixedly connected to the upper cover 217 by snap connection, screw connection or other methods. The first storage cavity 211 and the second storage cavity 212 are symmetrically arranged on the left and right sides of a side of the inner cover 216 away from the cover body 200. The inner cover 216 is also provided with an escape groove for escaping the roller 125.

[0044] As shown in Fig. 3 and Fig. 5, optionally, the inner contour of the first receiving cavity 211 matches the outer contour of the folded first side panel 300. The inner contour of the second receiving cavity 212 matches the outer contour of the folded second side panel 400.

[0045] Specifically in this embodiment, the left and right sides of one side of the inner cover 216 away from the upper cover 217 are sunken to form a first storage cavity 211 and a second storage cavity 212. The first storage cavity 211 and the second storage cavity 212 are both fan-shaped, ensuring that the first side panel 300 can be stored in the first storage cavity 211 after being folded, and ensuring that the second side panel 400 can be stored in the second storage cavity 212 after being folded, thereby improving the reliability of the heating device 10.

[0046] The first side plate 300 and the second side plate 400 can be connected to the left and right sides of the cover 200 by snapping, plugging, screwing or other methods. The first side plate 300 and the second side plate 400 can be connected to the left and right sides of the heating body 100 by snapping, plugging, screwing or other methods.

[0047] As shown in Fig. 5 and Fig. 6, in one embodiment, the left and right sides of the cover body 200 are provided with a first connection part 213. The left and right sides of the heating body 100 are provided with a second connection part 111. The upper part of the first side plate 300 and the upper part of the second side plate 400 are provided with a third connection part 311 connected to the first connection part 213. The lower part of the first side plate 300 and the lower part of the second side plate 400 are provided with a fourth connection part 312 connected to the second connection part 111. In this way, the first side plate 300 and the second side plate 400 can be installed on the cover body 200 through the first connection part 213 and the third connection part 311, and the first side plate 300 and the second side plate 400 can be installed on the heating body 100 through the second connection part 111 and the fourth connection part 312, thereby improving the convenience of assembling the heating device 10.

[0048] The number and location of the first connection portion 213, the second connection portion 111, the third connection portion 311, and the fourth connection portion 312 can be flexibly adjusted according to actual use needs. Specifically, in this embodiment, the first connection portion 213 and the third connection portion 311 are detachably connected, and the second connection portion 111 and the fourth connection portion 312 are detachably connected. In this way, the first side panel 300 and the second side panel 400 can be removed from the heating device 10 for maintenance or replacement, thereby increasing the service life of the heating device 10.

[0049] As shown in Fig. 5 and Fig. 6, optionally, the first connection part 213 is set as a buckle hole, the second connection part 111 is set as a buckle slot, the number of the buckle hole and the number of the buckle slot are both at least one, the buckle holes on the left and right sides of the cover body 200 are arranged at intervals along the width direction of the cover body 200 (the direction shown in A in Fig. 2), the third connection part 311 is set as a first buckle strip, the number of the first buckle strips is the same as the number of the buckle holes, and each first buckle strip is buckled with each buckle hole. The buckle slots on the left and right sides of the heating body 100 are arranged at intervals along the width direction of the heating body 100 (the direction shown in A in Fig. 2), the fourth connection part 312 is set as a second buckle strip, the number of the second buckle strips is the same as the number of the buckle slots, and each second buckle strip is buckled with each buckle slot.

[0050] Specifically in this embodiment, the number of button holes is eight, and the eight button holes are respectively arranged on the inner side wall of the side away from each other of the first storage cavity 211 and the second storage cavity 212. The number of button grooves is four, and the four button grooves are respectively arranged on the left and right sides of the top surface of the heating body 100. The upper part of the first side plate 300 and the upper part of the second side plate 400 are each provided with four first clip strips. The lower part of the first side plate 300 and the lower part of the second side plate 400 are each provided with two second clip strips.

[0051] As shown in FIG6 , in one embodiment, the first side panel 300 and the second side panel 400 are both configured as flexible panels. A first side groove 313 is provided at the upper portion of the flexible panel, and a second side groove 314 is provided at the lower portion of the flexible panel. The first side groove 313 and the second side groove 314 are both configured to bend inward when the flexible panel is in a folded state. In this way, the strength at the first side groove 313 and the strength at the second side groove 314 are both low, ensuring that when the cover body 200 switches from the open position to the closed position, the upper portion of the flexible panel folds inward at the first side groove 313, and the lower portion of the flexible panel folds inward at the second side groove 314, thereby ensuring that the two flexible panels can be folded and stored in the first storage cavity 211 and the second storage cavity 212, respectively, thereby improving the reliability of the heating device 10.

[0052] It should be noted that both the first side groove 313 and the second side groove 314 are thin-walled structures. The two first side grooves 313 and the two second side grooves 314 are respectively located on the side where the two flexible plates are close to each other.

[0053] As shown in Fig. 1 and Fig. 4, in one embodiment, the rear end of the cover 200 is rotatably connected to the heating body 100, so that the cover 200 can be rotated to an open position and a closed position. In this way, the cover 200 can rotate along a fixed path to stably and reliably switch back and forth between the open position and the closed position, thereby improving the reliability of the heating device 10.

[0054] In other embodiments, the cover 200 may also be movably connected to the heating body 100 via a flexible structure.

[0055] As shown in Fig. 4 and Fig. 5, optionally, the first side plate 300 and the second side plate 400 are both configured as flexible plates, and a folding groove 315 is provided in the middle of the flexible plate, and the extension line of the folding groove 315 intersects with the rotation axis of the cover body 200, and the folding groove 315 is configured to bend outward when the flexible plate is in a folded state. In this way, the strength at the folding groove 315 is relatively low, ensuring that when the cover body 200 switches from the open position to the closed position, the flexible plate can be folded in half and stored in the first storage cavity 211 and the second storage cavity 212, thereby improving the reliability of the heating device 10.

[0056] It should be noted that the folding groove 315 is a thin-walled structure. The two folding grooves 315 are respectively located on the sides of the two flexible plates that are close to each other.

[0057] Specifically in this embodiment, when the cover body 200 is switched from the open position to the closed position, the two first side grooves 313 and the two second side grooves 314 are both bent 90° toward the inside of the heating device 10, and the two folding grooves 315 are both bent 180° toward the outside of the heating device 10, so that the two flexible plates are in a folded state and are respectively stored in the first storage cavity 211 and the second storage cavity 212.

[0058] In one embodiment, the first side panel 300 and the second side panel 400 are both non-foldable structures. One end of the first side panel 300 and one end of the second side panel 400 are both rotatably connected to one of the heating body 100 and the cover body 200, and the other end of the first side panel 300 and the other end of the second side panel 400 are both detachably connected to the other of the heating body 100 and the cover body 200. In this way, when heating is needed, the cover body 200 is rotated toward the closed position, and the first side panel 300 and the second side panel 400 are both rotated toward the outside of the heating device 10; when the cover body 200 is rotated to the open position, the first side panel 300 and the second side panel 400 are both detachably connected to the corresponding one of the heating body 100 and the cover body 200. At this time, the first side panel 300 and the second side panel 400 are both in a vertical state, and are correspondingly arranged with the heating body 100 and the cover body 200 to form a heating space, reduce the heat loss rate, and achieve the effect of heat preservation and energy saving. When storage is required, release the detachable connection between the first side panel 300 and the corresponding one of the heating body 100 and the cover body 200, release the detachable connection between the second side panel 400 and the corresponding one of the heating body 100 and the cover body 200, move the first side panel 300 and the second side panel 400 toward the inside of the heating device 10, and rotate the cover body 200 toward the closed position; when the cover body 200 is rotated to the closed position, the first side panel 300 and the second side panel 400 are both in a horizontal state and are stored between the heating body 100 and the cover body 200, so that the height of the heating device 10 is significantly reduced, which is convenient for storage, organization and placement, and improves the practicality and user experience of the heating device 10.

[0059] As shown in FIG. 4 and FIG. 7 , in one embodiment, the heating device 10 further includes a rotating member 600 , and the rotating member 600 is used to rotatably connect the cover body 200 and the heating body 100 .

[0060] The rotating member 600 may be configured as a hinge, a hinge or other rotating connection structures. The number of the rotating members 600 may be flexibly adjusted according to actual use requirements.

[0061] Specifically in this embodiment, the rotating member 600 is configured as a hinge, and the number of hinges is at least one. Each hinge is arranged at intervals along the length direction of the heating body 100 (the direction shown by B in FIG. 2 ), and both ends of each hinge are respectively fixedly connected to the rear of the heating body 100 and the rear of the cover body 200. Specifically, one end of the hinge is fixedly connected to a surface of the inner cover 216 close to the upper cover 217, and the other end is fixedly connected to the side surface of the rear of the base 113. There are two hinges, and the two hinges are symmetrically arranged on the left and right sides of the rear of the heating device 10.

[0062] The hinge can be fixedly connected to the rear of the heating body 100 and the rear of the cover body 200 by screwing, snapping or other methods.

[0063] The suspension structure 500 may be any structure in the prior art that can make the cover body 200 suspend in the open position.

[0064] As shown in FIG. 4 and FIG. 7 , in one embodiment, the suspension structure 500 includes a damping member 511, which is mounted on the heating body 100 and frictionally matched with the cover body 200. Thus, when the cover body 200 rotates to the open cover position, the damping member 511 rubs against the cover body 200 to apply friction to the cover body 200, so that the cover body 200 can stop at the open cover position, with a simple structure, convenient operation, and low cost.

[0065] Specifically in this embodiment, the damping member 511 is configured as a damping block, which can be fixedly mounted on the heating body 100 by snap-fitting, plugging, screwing or other methods. In other embodiments, the damping member 511 can also be configured as a damping pad, a damping sleeve or other damping structure.

[0066] As shown in Fig. 7, optionally, a first sink 122 is provided at the rear of the heating body 100, and the damping member 511 is installed on the first sink 122. In this way, the first sink 122 can play a role in limiting and positioning, ensuring that the damping member 511 can be quickly and accurately installed on the heating body 100, thereby improving the convenience of the heating device 10.

[0067] Specifically in this embodiment, the first sink 122 can be formed by stamping the tail of the base 113 .

[0068] As shown in Fig. 4 and Fig. 7, in one embodiment, the cover body 200 is provided with a friction boss 214, and the friction boss 214 is frictionally matched with the damping member 511. In this way, the cover body 200 is frictionally matched with the damping member 511 through the friction boss 214, so that the position of the damping member 511 can be flexibly adjusted according to the needs of use, thereby improving the practicality of the heating device 10.

[0069] As shown in FIG. 4 and FIG. 7 , optionally, the cover body 200 includes an upper cover 217 and an inner cover 216 , the inner cover 216 is located between the upper cover 217 and the heating body 100 and is fixedly connected to the upper cover 217 , and the friction boss 214 is disposed at the rear of the inner cover 216 .

[0070] Specifically in this embodiment, the friction boss 214 and the inner cover 216 are an integral structure, for example, the friction boss 214 can be formed by stamping the tail of the inner cover 216. In other embodiments, the friction boss 214 and the inner cover 216 can also be a separate structure, for example, the friction boss 214 can be installed on the tail of the inner cover 216 by snap connection, screw connection or other fixed connection methods.

[0071] The number of the damping elements 511 and the number of the friction bosses 214 can be flexibly adjusted according to actual use requirements.

[0072] As shown in Fig. 4 and Fig. 7, optionally, the number of the damping members 511 is at least one, and each damping member 511 is arranged at intervals along the length direction of the heating body 100, and each of the damping members 511 is frictionally matched with the friction boss 214. In this way, by increasing the number of damping members 511, the number of friction surfaces between the damping members 511 and the friction boss 214 is increased, ensuring that the cover body 200 can stably and reliably hover in the open position, thereby improving the reliability of the heating device 10.

[0073] Specifically in this embodiment, the number of friction bosses 214 is one, and is along the length direction of the cover body 200 (as shown in the B direction in FIG. 2 ). The number of damping members 511 is two, and the two damping members 511 are arranged at intervals along the length direction of the heating body 100, and both are frictionally matched with the friction bosses 214. The number of first sinkers 122 is the same as the number of damping members 511, and each damping member 511 is arranged corresponding to each first sinker 122.

[0074] As shown in Fig. 4 and Fig. 5, optionally, the friction boss 214 is provided with a first arc surface, and the damping member 511 is provided with a second arc surface, and the first arc surface is in surface contact with the second arc surface and frictionally cooperates with the second arc surface. In this way, the friction boss 214 and the damping member 511 are frictionally cooperated through the first arc surface and the second arc surface, so that the friction area between the single damping member 511 and the friction boss 214 is increased, ensuring that the cover body 200 can stably and reliably hover in the open position, thereby improving the reliability of the heating device 10.

[0075] Specifically in this embodiment, the axis of the first arc surface, the axis of the second arc surface, and the rotation axis of the cover 200 coincide. Each damping member 511 is provided with a second arc surface. The number of the first arc surfaces is the same as the number of the second arc surfaces.

[0076] As shown in Fig. 4 and Fig. 7, in one embodiment, the friction boss 214 is provided with a first limit portion 215, and the heating body 100 is provided with a second limit portion 112, and the second limit portion 112 is configured to cooperate with the first limit portion 215 when the cover body 200 is rotated to the open cover position. In this way, the first limit portion 215 and the second limit portion 112 can cooperate to limit the maximum rotation angle of the cover body 200, so as to prevent the cover body 200 from rotating too much and causing the first side plate 300 and the second side plate 400 to be damaged, thereby improving the reliability of the heating device 10.

[0077] The first limiting portion 215 and the second limiting portion 112 can be configured as limiting blocks, limiting protrusions or other limiting structures. The number of the first limiting portion 215 and the second limiting portion 112 can be flexibly adjusted according to actual use needs.

[0078] Specifically in this embodiment, the number of the first arc surface, the damping member 511 and the first sink 122 are two. The second limit portion 112 and the base 113 are an integrated structure and are located between the two first sinks 122. The first limit portion 215 is located at the middle of the friction boss 214, and the two first arc surfaces are located on the left and right sides of the first limit portion, ensuring that the force at the friction boss 214 is uniform when the first limit portion 215 collides with the second limit portion 112 to improve the reliability of the heating device 10.

[0080] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0081] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0082] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0083] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0084] It should also be understood that when explaining the connection relationship or positional relationship of elements, although not explicitly described, the connection relationship and positional relationship are interpreted as including an error range, which should be within the acceptable deviation range of a specific value determined by those skilled in the art.
